WINDMILL-PITIVIAN.

Specification of Iietters Patent.

Patented Apr. 8, 1913.

Application filed September 16, 1911. Serial No. 649,679'l To @ZZ whom tmay concern.'

Be it known that I, GEORGE F. KREGEL, a citizen of the United States,residing at Nebraska City, in the county of Otoe and State of Nebraska,have invented new and useful Improvements in Wind1nill-Pitmen, of whichthe following is a specification.

The present invention relates to certain novel and useful improvementsin wind mill pitmen.

In carrying out my invention, it is my purpose to provide a pitmanwhereby a direct lift is attained on the upward stroke of the pump rodor staff. Furthermore, I provide a pitman having a swiveled joint, thepitman block at the joint being slot-ted at the side thereof; so thatthe complete pitman may be removed from the pivot post of the mill whileat the same time the ordinary pull out chain and wire of the wind millmay remain in place to hold the mill out of gear.

It is also my intention to provide a simple, compact, reliable andeiiicient wind mill pitman which is composed of relatively few parts,and these so constructed that they may be readily assembled in positionfor use, and quickly dismantled when desired.

With the above-recited objects, and others of a similar nature in view,the invent-ion consists in the construction, combination and arrangementof parts, set forth in and falling within the scope of the appendedclaims.

In the drawing :--Figure 1 isa view in side elevation of my wind millpitman, showing the same attached to the crank pin of the mill at oneend, and to the pump staff at the other end. Fig. 2 is a fragmentaryside elevation, partly in section of the device shown in Fig. 1.sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a similar viewtaken on the line 4 4 of Fig. 1. Fig. 5 is a view of the swivelpartially in elevation and partially in section, showing the manner ofassembling the same.

Referring now to the accompanying drawings in detail, the numeralldesignates a portion of the crank pin of the wind mill to which isconnected a strap 2 through the medium of the cross bolts 3. Theopposite end of the strap is rolled back upon itself to form the bearingor eye 4 which is connected to the block 5 of the pitman by means of thecross pin or bolt 6, the end ofthe strap carrying the eye being insertedin the Fig. 3 is a cross socket 7 in the block, the pin or bolt 6passing through alining bores 88 in t-he block and through the eye ofthe strap, the pin being secured in position by. any suitable means suchas the cotter pin 9. To the ends 10-10 of the block are secured the endportions 11-11 of the Vparallel bars 12 of the pitman, the opposite endsof said bars being connected as at 13 to the pitman block 14. Thislatter is formed with a recess 15 which is provided with a reducedentra-nce or opening 16, communicating therewith, whereby a shoulder 17is formed, such shoulder being in the nature of an internal ange.Adapted to be connected to the pitman block 14 is a swivel block 18formed of the two sections 19-19, each section terminating at its outerend in a head 20, which when the parts are assembled, is adapted to liein the `recess 15, the inner faces 21 of each head section being beveledupwardly and inwardly as clearly shown in the drawings. Each swiveledblock section 19 is connected by bolts 22 to a bar 23, the two parallelbars 23 being suitably spaced apart and connected at their lower ends tothe pump rod 24 by means of the bolts 25. l

It is to be noted that the swivel block sections are each provided witha reduced neck portion 26 which receives the shoulder or flange at therecessed portion of the pitman block 14.

From the above description, taken in connection with the accompanyingdrawings, the construction and manner of assembling and employing thepitman will be readily apparent. The strap 2 having been connected withthe crank pin, the pitman is attached to the eye 4 of the strap by meansof the pin G, and the swivel block is connected to the opposite pitmanblock 14, as shown in Fig. 5, that is to say, one head section at a timeis inserted in the recess portion of the block, so that when the twobars 23 are brought into parallelism so that the adjacent faces of theswivel block sections lie in contact, the swivel block will be movablysecured to the pitman block. The opposite ends of the bars 23 aresecured to the pump staif or rod by means of the bolts 25 or the like.The pitman block 14 which forms the swivel casting is slottedlongitudinally as at 27, so that the pull-out chain and wire, which isnot shown in the drawings, but which passes by the upper pitman block 5,and through the lower pitman block 14 and swivel blocks may be operatedto hold the ymill out of gear, while the pitman may be simple, strongand reliable form of pitman which is especially adapted for wind millsand by means of which a direct pumping stroke may be attained.

I claim l. A pitman comprising a block, a strap connected to one endthereof, a second block formed with a recess therein, a swivel blockformed of two sections each having a head portion adapted when theswivel block is assembled to lie and swivel Within the recessed portionof the second block, said sec tions being provided with proximatebeveled surfaces whereby the sections may be inserted in the recess andremoved therefrom, and connecting bars secured to the sections of theswivel block.

2. A pitman comprising a block, a strap connected to one end thereof, asecond block formed with a recess therein and having a shoulderextending into the recess, a swivel block formed of two sections eachhaving a head portion adapted when the swivel block is assembled to lieand swivel within the re cessed portion of the second block and engagethe shoulders thereof, said sect-ions being also provided with proximatebeveled surfaces whereby the sections may be inserted into and removedfrom the recess in the said block, and connecting bars secured withinthe recessed portion of the second block and engage the shoulderthereof, said sections having their adjacent surfaces beveled at theextremities within the recess whereby the blocks may be inserted intoand removed from the recess in the block, and connecting bars betweenthe sections of the block and the pump rod and spaced apart.

In testimony whereof I aiiix my signature in presence of two witnesses.
